Setting the message headers using non US-ASCII data

The email message protocols state that all message headers are limited to characters in the US-ASCII character set. In order to use characters in other languages that are outside of the US-ASCII character set the data must be encoded. The EmailMessage class handles this for you provided that you instruct it which character set to use when encoding the message.

Example

// create new EmailMessage instance

EmailMessage msg = new EmailMessage();

// set subject encoding data using iso-8859-1 character set

msg.setSubject("Mit herzlichen Grüßen","iso-8859-1");
